The M433 Grenade, called the M203 Grenade in games, is a type of grenade launcher shell ammunition featured in all three S.T.A.L.K.E.R. games.


The M203 Grenade is a 40x46mm breach-loading, low-velocity, anti-armor and anti-personnel grenade shell that detonates when it hits a hard object. It has a High-Explosive Dual Purpose warhead with both a shaped charge designed to penetrate armor and a shrapnel charge to attack nearby personnel. When it detonates, it releases a powerful, short-range explosion that would disorient and/or kill everyone in its blast radius. The 40mm grenade shell is commonly used for NATO type grenade launchers.

Used by the: M203 Grenade Launcher and the FT-200M's integral underbarrel grenade launcher. The cut Bulldog 6 m209 in S.T.A.L.K.E.R.: Shadow of Chernobyl also uses these grenades.
